3.2 Principle of operation
The VEGACAP 67 is a point level sensor for bulk solids.The probe is
designed for high temperature applications.
Probe, measured product and vessel wall form an electrical capacitor.
Thecapacitanceisinuencedbythreemainfactors.
1
2
3
Fig. 3: Functional principle - Plate capacitor
1 Distance between the electrode surfaces
2 Size of the electrode surfaces
3 Type of dielectric between the electrodes
The probe and the vessel wall are the capacitor plates.The measured
product is the dielectric. Due to the higher dielectric constant of the
product compared to air, the capacitance increases as the probe is
gradually covered.
The capacitance change is converted by the electronics module into
a switching command.
Depending on your requirements, VEGACAP 67 with two-wire elec-
tronicscanbeconnectedtodierentcontrollers.Compatiblecontrol-
lers are listed in chapter " Technical data".
Thedataforpowersupplyarespeciedinchapter"Technical data".
3.3 Adjustment
The probe can be adapted to the dielectric constant of the product
directly on the electronics module.
A switching command can be triggered when the probe is covered or
laid bare.
Ontheelectronicsmoduleyouwillndthefollowingdisplayand
adjustment elements:
• Control lamp for indication of the device status.
3.4 Packaging, transport and storage
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
based on ISO 4180.

4.1 General instructions
Note:
For safety reasons, the instrument must only be operated within the
permissibleprocessconditions.Youcannddetailedinformationon
the process conditions in chapter " Technical data" of the operating
instructions or on the type label.
Hence make sure before mounting that all parts of the instrument ex-
posed to the process are suitable for the existing process conditions.
These are mainly:
• Active measuring component
• Processtting
• Process seal
Process conditions in particular are:
• Process pressure
• Process temperature
• Chemical properties of the medium
• Abrasionandmechanicalinuences
In general, VEGACAP 67 must be mounted vertically.The instrument
must be mounted in such a way that the probe is at the height of the
requested switching point.
Before beginning the welding work, remove the electronics module
from the sensor. By doing this, you avoid damage to the electronics
through inductive coupling.
Ground the probe before welding directly on the rod or cable.
Deviceswiththreadedttingarescrewedintotheprocessttingwith
a suitable wrench via the hexagon.
See chapter " Dimensions"forwrenchsize.
Warning:
The housing or the electrical connection may not be used for screw-
ing in! Depending on the device version, tightening can cause dam-
age, e. g. to the rotation mechanism of the housing.
With threaded versions, the housing must not be used to screw in the
instrument! Applying tightening forces on the housing can damage its
internal parts.
Use the hexagon for screwing in.
Use the recommended cables (see chapter " Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cablegland.Rainandcondensationwatercanthusdraino.This

applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.
To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Fig. 4: Measures against moisture ingress
Theprocessttingmustbesealedifthereisgaugeorlowpressure
in the vessel. Before use, check if the sealing material is resistant
against the measured product and the process temperature.
Themax.permissiblepressureisspeciedinchapter"Technical
data" or on the type label of the sensor.
Metal vessel
Make sure that the mechanical connection of the probe to the vessel
iselectricallyconductivetoensuresucientgrounding.
Use conductive seals, such as those made of copper or lead, etc.
Insulatingmeasures,suchascoveringthethreadwithTeontape,
can interrupt the necessary electrical connection with metal vessels.
For this reason, ground the probe on the vessel or use a conductive
seal material.
Non-conductive vessels
In non-conductive vessels, e.g. plastic tanks, the second pole of the
capacitor must be provided separately.
Metric threads
In the case of instrument housings with metric thread, the cable
glands are screwed in at the factory.They are sealed with plastic
plugs as transport protection.
You have to remove these plugs before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it is
not possible to have the cable entries screwed in at the factory.The
free openings for the cable glands are therefore covered with red dust
protection caps as transport protection.
Prior to setup you have to replace these protective caps with ap-
proved cable glands or close the openings with suitable blind plugs.

4.2 Mounting instructions
Duetotheeectsofagitators,equipmentvibrationorsimilar,thelevel
switch can be subjected to strong lateral forces. For this reason, do
not use an overly long electrode for VEGACAP 67, but check if you
canmountashortlevelswitchonthesideofthevesselinhorizontal
position.
Iftheinstrumentismountedinthellingstream,unwantedfalse
measurement signals can be generated. For this reason, mount the
instrument at a position in the vessel where no disturbances, e.g. from
llingopenings,agitators,etc.,canoccur.
This applies particularly to instrument versions with a longer probe.
Fig.5:Inowingmedium
The probe should protrude into the vessel to avoid buildup. For that
reason,avoidusingmountingbossesforangesandscrewedttings.
This applies particularly to use with adhesive products.
In silos with bulk solids, material cones can form which change the
switching point. Please keep this in mind when installing the sensor
in the vessel.We recommend selecting an installation location where
the probe detects the average value of the material cone.
The probe must be mounted in a way that takes the arrangement of
thellingandemptyingaperturesintoaccount.
